Objectives: To outline the prevalence and disparities of vision problems among school-aged urban minority youth, causal pathways through which vision problems adversely affects academic achievement, and proven or promising approaches for schools to address these problems. Methods: Literature review. Results: More than 20% of school-aged youth have…

Purpose: Traditional school vision screening has focused on the examination of distance vision using screenings such as the "School Vision Screening" used in this study. No vision screenings for determining how well children can see print or pictures at close distances are administered on a regular basis. The purpose of the study was to…

The authors conducted a systematic review to examine whether vision-related assessments can predict the driving performance of individuals who have low vision. The results indicate that measures of visual field, contrast sensitivity, cognitive and attention-based tests, and driver screening tools have variable utility for predicting real-world…

The assessment of visual acuity in the preverbal child is reviewed. Four techniques are discussed: optodinetic nystagmus, forced choice preferential looking, visually evoked potential, and electroretinography. Development of binocularity and refractive changes are traced. (CL)

By testing students for depth perception, instructors can identify those students whose monocular vision prevents them from properly drawing three-dimensional objects. (SK)

Special Olympics provides sporting opportunities for people with intellectual disabilities (ID), and Lions Clubs International Opening Eyes GB offers vision screening for athletes at Special Olympics Games. Opening Eyes GB screened the vision of 505 UK athletes at its inaugural event in 2001. The results were analysed and are presented here.…

The booklet, another in a series for parents of deaf blind children, presents information in large type about the nature and cause of deaf blindness. A drawing of the ear is followed by a simplified discussion of the ear's functioning and definitions of terms (such as spondee threshold) used in hearing testing and hearing loss. Similarly, a…

To determine which children in the Head Start program may have vision problems, Head Start teachers and staff do vision "screening." This booklet demonstrates how to do the screening using the Snellen "E Chart." Trouble signs that the test administrator should be aware of are listed, and vision scores are explained simply.…

Compared was the incidence of lateral phoria, a tendency for the eyes to turn in or out, in 45 elementary grade learning disabled children and 364 children in regular elementary education classes. (DB)

The relationship between vision and reading achievement is complex. In this paper, a number of terms relating to vision are defined and some of the limitations of specific measures of vision are discussed. In order to relate vision to reading, it is necessary to segment arbitrarily the continuous process of vision into a series of subsystems, or…

This bulletin explains some of the visual characteristics of children and youth, examines critically the vision screening tests used in some schools, and explains the problems resulting from their use. Chapters deal in turn with vision and visual characteristics, the professional eye examination, visual screening tests, problems in referrals from…

In 73 children (6-13 years old) with reading difficulty, ophthalmological evaluation showed that 18 had overt refractive errors, 18 dyslexia and no ocular anomalies, and 37 impaired fusional amplitudes, 24 of whom were dyslexic. In all Ss with poor fusional amplitudes the reading mechanism could be improved with orthoptic exercises. (Author/CL)

The purpose of this book goes beyond a procedural manual or a "how-to, cook book" approach to vision screening. This book is intended to assist the new school nurse in fully understanding the screening process, comprehending the pathophysiology of the several visual functions, which may be assessed in the school setting. This book is also intended…
